Denizen and fellow blogger Alan K. Henderson tells us of a group of primates that apparently have formed the 187th Fighting Banana Brigade™.
A band of males, up to 20 or so, will assemble in single file and move to the edge of their territory. They fall into unusual silence as they penetrate deep into the area controlled by the neighboring group. They tensely scan the treetops and startle at every noise. “It’s quite clear that they are looking for individuals of the other community,” Dr. [John (UMichigan)] Mitani says.
When the enemy is encountered, the patrol’s reaction depends on its assessment of the opposing force. If they seem to be outnumbered, members of the patrol will break file and bolt back to home territory. But if a single chimp has wandered into their path, they will attack. Enemy males will be held down, then bitten and battered to death. Females are usually let go, but their babies will be eaten.
Hmmm.  Wonder if that explains this?
Quick, someone had better resurrect Chuck Heston.
Mheh.
